"I was prescribed Biaxin for bronchitis. I've taken three pills. I have an horrible taste in my mouth all the time along with severe dry mouth. My stomach is tossing and turning, making the loudest noises I've ever heard a stomach make! I haven't had problems with nausea/vomiting but the diarrhea from this is horrendous! On the second day of taking this I got this huge burst of energy and wanted to clean every inch of my house and rearrange each room! (sort of strange as I'm still coughing constantly and having a very hard time breathing) I'm also having trouble sleeping. I'm not sure that I will be taking anymore of these."
